Île des Morts

Roscanvel (French pronunciation: ​[ʁɔskɑ̃vɛl]; Breton: Roskañvel) is a commune in the Finistère department of Brittany in north-western France.

Quélern is a hamlet in Roscanvel, in the department of Finistère (Brittany), in western France.

The fort Quélern or réduit de Quélern is a castle and prison in the commune of Roscanvel in France.

Île Longue (French for "Long Island") is a peninsula of the roadstead of Brest in the department of Finistère in the Brittany region. It is the base of the SNLE, the French ballistic missile submarines, and as such one of the most secretive and heavily defended places in France.

Tremet is a hamlet on the Roscanvel peninsula in France. The gun batteries located here are part of the defences of the goulet de Brest, forbidding ships from entering the bay of Camaret-sur-Mer. The site had been occupied by the military since 1694 (a battery was probably sited here in Vauban's defensive scheme) and was updated several times in the 18th and 19th centuries. The battery became a heavy anti-aircraft post in 1955 as part of the outer defences of Brest's military fort - part of that battery is still part of the military land around Quélern and not open to the public.

Îlot du Diable is a gun battery built to support fort de la Fraternité in the defensive system around the goulet de Brest in France. It is sited on the peninsula of Roscanvel and is accessible by a small bridge. The battery was razed in the 19th century, and in 1890 on its site was built a bunker with an electricity generator. A casemate was then added by the Germans in 1942. A small observation is still to be found at the summit of the site, near a former lime kiln.

The siege of Fort Crozon or the siege of El Leon was a land and sea engagement that took place as part of Spain's Brittany Campaign late in the French wars of religion and the Anglo-Spanish War (1585–1604). The siege was fought between 1 October and 19 November 1594 and was conducted by English and French troops against a Spanish fort constructed on the Crozon Peninsula near Brest. After a number of assaults were repelled, a Spanish relief force under Juan del Águila attempted to relieve the garrison, but it was delayed by French cavalry and could not reach the garrison in time.An assault by the English using a deceitful ruse ended the siege when the defenders were all but put to the sword. The victory proved decisive in two ways. First, it denied the Spanish an important large independent base and port from which to operate in Brittany against the English and Dutch. Second, the Spanish had lost most of their support from the French Catholic League, and as a result enabled the French king Henry IV to declare war on Spain.

The Pointe des Espagnols is the north-east extremity of the Roscanvel peninsula, an outgrowth of the Crozon peninsula closing off the roadstead of Brest. It also marks the south-east limit of the goulet de Brest (the other limits are marked by pointe des Capucins, pointe du Petit Minou and pointe du Portzic). Formed by a cliff that is more than 60m high, at whose summit and base are the remains of fortifications and barracks, the point reaches towards the north-east via the rocher de la Cormorandière, marked by a pole. The straight channel situated between the point and the rocher is the location for strong currents which affect the roadstead. This strategic position, facing Brest, was already noted by the Duchy of Brittany, who sited a fortlet there in 1387 (now lost). In 1594, Spaniards landed here and were only dislodged after several battles - it was in this period that the cape first took on its present name.

La pointe de Cornouaille is a cape to the north of the hamlet of Kerviniou in France. They are both situated on the Roscanvel peninsula and, facing as it does the Fort du Mengant, a battery on the point forms part of the defences of the goulet de Brest. Known defences on the site include: Lower battery (1694) - built to plans by Vauban Tour modèle n°1 (1813) - see Tour-modèle type 1811 Batterie de rupture sous roc (1888) Batterie du plateau (1897) Batterie de DCA allemande (1943, German) Torpedo-boat battery (German)

The batteries de Kerviniou are artillery batteries built in the late 19th and early 20th centuries, and are made up of an upper battery (1891) and an underground magazine (1891) Located on the Roscanvel peninsula facing the Fort du Mengant, they are a late addition to the defences of the goulet de Brest (a lower battery near the site, dating to 1695, has not yet been found). Demilitarised in 1915, they are open to the public.

Camaret Bay (French: Anse de Camaret) is a small bay on the north coast of Brittany, France. In 1694 it was the site of the battle of Camaret, a naval action between French and English forces, which culminated in a disastrous amphibious landing by the English as part of an attempt to seize the nearby port of Brest.

The Goulet de Brest (French pronunciation: ​[ɡulɛ də bʁɛst]) is a 3-km-long strait linking the roadstead of Brest to the Atlantic Ocean. Only 1.8 km wide, the goulet is situated between the Pointe du Petit Minou and the Pointe du Portzic to the north and the îlot des Capucins and the Pointe des Espagnols to the south. At each turn of the tide, the ocean refills the roadstead in a current that can attain 4 to 5 knots. Sailing ships would thus wait in the cove of Camaret-sur-Mer for a favourable current to carry them into the goulet. On 2 January 1793, the Childers Incident – the first shots of the war between Great Britain and France during the French Revolutionary Wars – took place in the goulet.
